Vape Battery Chargers: Best of the Best

The battery chargers on this list can service a wide variety of batteries, although two are compatible only with 18650 cells. The rest are multi-platform, meaning they can take various cells, but they were also chosen based on their performance, their features, their price point as well as their ease-of-use.

  • It is not 100% accurate

The asMODus D-500-TY battery analyzer and charger is a multi-use unit that charges as well as analyzes batteries. The unit has only a single battery bay, so it does not have the same capability as multiple-bay units.

The D-500-TY has the aim of informing vapers on three essential battery specs: the resistance, the capacity, and the max output capacity. The device has four modes, and a four-button control panel to switch between modes. The LCD above the panel also lets vapers know all they want to know about their cells.

When users insert their cell to charge it or check the resistance, the capacity or the output, they have to select the mode, using the “Mode” button. The device beeps at specific points, like when it analyzes the resistance.

7/10 icon-question Review score
charging battery type:
Li-Ion, Ni-MH, NiCd
input:
AC 100 - 240V 50 / 60Hz 1A (max)
output voltage:
4.2V + / - 1pct, 1.48V + / - 1pct

Pros:

  • Full versatility as it can fit many battery types
  • Button-less design
  • Convenient and durable

Cons:

  • No LCD screen
  • No external USB port

The ESYB S6 6-bay vape battery charger features six independent battery slots with metal rails that can fit almost any size battery. The unit can handle everything from double and triple-A batteries to the larger 18650 and 26650 variety. Each bay has its LED that monitors and shows the current status of the cell.

The ESYB S6 also has two charging modes, CC (constant current) and CV (constant voltage). Each bay has a different capacity. The four center bays can hold four Li-Ion 18650 batteries and use 0.5A charging. At the same time, users can install two more cells on the outer two bays to enable 1A charging for those two cells.

The S6 comes with various safety features as well. It stops charging automatically when the process is done. The S6 also comes with reverse polarity, overcharging and over-voltage protection. The entire charger comes encased in a fire-resistant, ABS plastic to keep it sturdy and durable.


Types of Battery Chargers

The vape battery chargers here, no matter if they are 18650 battery chargers, 20700 battery chargers or 21700 vape battery chargers, all have a lot in common. Only one is an exclusive 18650 battery charger, while the others can fit various sizes and types.

All chargers should at least have the following:

  • Reverse polarity protection: keeps batteries from charging when they are installed improperly
  • Over-charging protection: stops charging a cell once the process is complete
  • Short-circuit protection: to protect against overcurrents and break the connection

One main difference between all these chargers is the number of slots they have. They have single, dual, triple, quad and sextuple slots for charging many batteries at the same time. For someone who is a heavy vaper, and has a lot of different box mods, a charger with multiple bays would be the best choice.

The vape chargers with many slots can also take several battery types, which make them perfect for non-vaping uses as well. Also, even if they are 18650 battery chargers, they can become 20700, as well as 21700 or 26650 battery chargers whereas a moderate to beginner vaper would go with the smaller, more manageable and easier-to-use, dual or triple slot chargers.

How to Charge Vape Batteries

All the best 18650 battery chargers, as well as all the best 20700, 21700 and 26650 battery chargers, come with standard safety features. These features do not mean that users should ignore basic battery safety rules. Rules like:

  • Never use or charge batteries with torn, broken or ripped wraps
  • Never leave batteries in the charger after they have finished charging (over-charging protection will solve this problem, but it is best to remove full cells)
  • Make sure the charger is compatible with the chemical elements inside battery (e.g., lithium-ion, lithium-polymer, NiCad, NiChrome, etc.)
  • Never force an ill-fitting battery into a slot, make sure the cell fits comfortably
  • If you have replaceable cells for your mod, charge them in an external unit; do not charge them via the device’s USB port

Which Charger Is Right For You?

The best 18650 or even best 26650 battery chargers might not be the “best” for everyone. Picking the best battery charger depends on how often and for what exactly you need batteries. A unit like the ESYB S6 that has six slots is perfect for people who need batteries all the time for whatever reason, vapes, flashlights, smoke detectors, personal electronics, etc..

While something like the Nitecore UM10 has only two battery bays, is smaller and therefore much more portable, while also having several non-charging features. The Nitecore UM10 can act as a data transfer point, as well as an external USB charger for other portable vape mods.

The Nitecore UM10 is suited more for people always on the go, and who need more than just a charger. With that said, people should pick the charger that best suits their needs. Whether it is for a triple-celled 18650 vape mod, or running a simple flashlight or having a portable back-up charger, these units can do it all.

Final Thoughts

Vape battery chargers have their place in the supply chain that supports the biggest and most potent vaping mods, namely 18650 box and mech mods. Without chargers, vaping wouldn’t exist, and choosing the best 18650 battery charger comes down to a few things.

Safety is first, so make sure they have several protections or even a heat-dissipating design that will prevent it from overheating. Then come the added features like LCD screens, intelligent, onboard microprocessors, as well as several ports to charge many batteries simultaneously.

With these characteristics checked off the list, the best 20700 battery charger or the best 21700 charger then comes down to personal preference, and with the selection above, it should not be a hard decision.
